DETAILED DESCRIPTION
[00018] Fig. 1 shows an exploded view of a caster 100 in accordance with one embodiment of the present invention. Caster 100 includes a caster yoke 102 having a pair of yoke sides 104a, 104b. A wheel 110 is retained by the caster yoke 102 at the latter' s spaced apart lower side portions 106a, 106b, by means of wheel bolt 112, washers 114 and wheel retaining nut 116 engaged to the wheel boltl 12. In some embodiments, the wheel is a "crown-point" wheel (i.e., has a ground contact surface comprising a rounded cross-section, rather than a flat cross-section). [00019] In some embodiments, and as seen in Fig. 5, the yoke sides 104a, 104b may be connected to one another at a top portion thereof by a lower rim 404 of a bearing housing 400. In such case, the yoke sides 104a, 104b may be welded, brazed or otherwise permanently fixed to the lower rim 404 to the bearing housing 400.
[00020] In other embodiments, the top portions of the yoke sides 104a, 104b may be connected to one another by a connecting strip formed of the same material as the yoke sides. In such case, the yoke sides and connecting material may be formed by stamping a flat metal sheet to form a yoke blank and then bending the strip-connected yoke sides 104a, 104b using a mandrel in a known manner. An opening may then be formed in the connecting strip to accommodate a bolt, pin or other fastener, as described further below, either before or after a housing affixed to the yoke to accommodate the shielded bearing, also as discussed further below.
[00021] Figs. 4A - 4E shows one embodiment of a bearing housing 400. The bearing housing 400 may have a generally cylindrical outer wall 402, a lower rim 404, an upper rim 406 and an inner wall 408 defining a passage through the bearing housing 400. Provided on the inner wall 408 of the bearing housing, proximate the upper rim 406, is a circumferential groove 410 configure to accommodate a retaining ring 130.
[00022] The inner wall 408 of the bearing housing 400 may be provided with a
circumferentially extending step 412 proximate the lower rim 404. The step 412 projects in a radially inward direction of the bearing housing 400. The step 412 is configured to support a bottom periphery of a cylindrical shielded bearing 120 thereon. Thus, the inner wall 408 of the bearing housing 400 may be considered to be a stepped inner wall. Between the step 412 and the lower rim 404, the inner wall 408 has a reduced diameter lower portion 414, whose diameter is smaller than that of the upper portion 406 of the inner wall 408.
[00023] The lower rim 404, in a side view thereof, is stepped, having two spaced apart cutouts 420a, 420b formed therein, resulting in two spaced apart raised sections 422, 424. Each raised section 422, 424 is defined between two parallel step portions 426a, 426b. Meanwhile, cutout 420a is defined by two collinear step portions 420a while cutout 420b is defined between two other collinear step portions 420b, the two collinear step portions 420a being generally parallel to the two collinear step portions 420b. Each cutout 420a, 420b has a downwardly facing corresponding abutment surface 428a, 428b. [00024] Fig. 5 shows one embodiment of how the yoke 102 may be constructed from the yoke sides 104a, 104b and the bearing housing. As seen in Fig. 5, the upper surface 105 of each yoke side 104a, 104b is in abutment with a downwardly facing abutment surface 428a, 428b of a corresponding cutout 420a, 420b formed in the lower rim 404 of the bearing housing. As stated above, the upper surface 105 of each yoke side 104a, 104b may be welded, brazed or otherwise permanently attached to the lower rim 404 of the bearing housing 400.
[00025] In the assembled caster, a shielded bearing 120 is located in the bearing housing 400, and the retaining ring 130 occupies the circumferential groove 410 to keep the shielded bearing 120 in place. The shielded bearing 120 may be a commercially available bearing having a generally cylindrical outer surface 122, a central opening 124, a generally annular top surface 126 surrounding the central opening 124 and a similarly annular bottom surface also surrounding the central opening 124 (and hidden from view in the figures). The shielded bearing 120 is selected to have an appropriate size and ABEC designation in light of its intended use. In one embodiment, the shielded bearing 120 has an ABEC-5 designation, a 1.375 inch OD outer surface and a 0.437 inch ID central opening 124.
[00026] In the embodiment seen in Fig. 1, the caster 100 is mounted to a horizontally extending leg 600 (shown in phantom in Fig. 1) of a chair or other piece of furniture, via the former's caster mounting assembly. As seen in Fig. 1, the caster mounting assembly 190 includes a bottom bolt 140, a lower nut 146 and a lower washer 146. The bottom bolt 140 includes a threaded bolt shaft 142 connected to a bolt head 144. In the assembled caster 100, the bolt head 144 can abut the bottom surface of the shielded bearing 120 which, as stated above, is kept in position by the retaining ring 130. The lower nut 146 and lower washer 148 are mounted on the threaded bolt shaft 142. In some embodiments, the lower nut 146 may abut the top surface 126 of the shielded bearing 120, thereby serving as a spacer 146, while the lower washer 148 may abut an underside of the leg tube 600. The far end of the threaded bolt shaft 142 may pass through the leg tube 600 and be affixed thereto via upper washer 150 and upper nut 152.
[00027] The caster 200 seen in Fig. 2 is generally similar to the caster 100 of Fig. 1 except for the caster mounting assembly. Therefore, the components in caster 200 which are identical to those in caster have not been labeled.
[00028] As seen in Fig. 2, the caster mounting assembly 290 includes a caster pin 240 having, at lower end thereof, a lower threaded portion 242 which passes through the central opening 124 of the shielded bearing 120 and threadingly engages a retaining nut 262 located below the shielded bearing 120.
[00029] In addition to its lower threaded portion 242, the caster pin 240 includes a lower shaft portion 244, an upper shaft portion 246 and an enlarged spacer portion 248 between the lower shaft portion 244 and the upper shaft portion 246. The enlarged spacer portion 248 has the largest diameter of any portion of the caster pin 240. The caster pin 240 is provided with a narrowed neck portion 250 proximate its upper end 252. The narrowed neck portion 250 is configured to receive a grip ring 272. The caster 200 thus is mounted to a chair or other piece of furniture by insertion of the caster pin's upper end 252 into a suitable aperture configured to receive and retain the caster pin 240.
[00030] In the assembled caster 200, the retaining nut 262 may be in abutment with the bottom surface of the shielded bearing 120. And in some embodiments, the spacer portion 248 may have a lower surface thereof abut the top surface 126 of the shielded bearing 120.
[00031] The caster 300 seen in Fig. 3 is generally similar to the caster 100 of Fig. 1 and the caster 200 of Fig. 2, except for the caster mounting assembly. Therefore, the components in caster 300 which are identical to those in casters 100 and 300 have not been labeled.
[00032] As seen in Fig. 3, the caster mounting assembly 390 includes a bolt-on type base plate
340. In some embodiments, the base plate 340 is made of steel. The base plate 340 includes a threaded shaft 342 projecting from its underside and a plate member 344 provided with a plurality of bolt holes 382.
[00033] In the assembled caster 300, the threaded shaft 342 passes through the central opening 124 of the shielded bearing 120 and threadingly engages a retaining nut 362 located below the shielded bearing 120. In the assembled caster 300, the retaining nut 362 can be in abutment with the bottom surface of the shielded bearing 120. As best seen in Figs. 6A and 6B, the threaded shaft 342 may be provided near its base with a spacer 346. The spacer 346 may be configured to abut the top surface 126 of the shielded bearing 120. In some embodiments, the spacer 346 may have one-piece unitary construction with the threaded shaft 342 while in other embodiments the spacer 346 may be in the form of a nut threadingly engaged to, and located at the base of, the threaded shaft 342.
[00034] From the foregoing, it should be evident that the fork assembly 107 comprising the yoke 102 having the housing 400 affixed thereto, the shielded bearing 120 and retaining ring 130 are common to all caster embodiments. Thus, a manufacturer, supplier or retailer may provide a first kit comprising: (a) a fork assembly 107 including the yoke 102 having the bearing housing 400 affixed thereto; (b) a retaining ring 130; and (c) the shielded bearing 120, and may further provide a second kit comprising one of the caster mounting assemblies 190, 290 or 390. A variation of this might be to provide a first kit comprising just the fork assembly 107 and the retaining ring, and a second kit comprising any one of the caster mounting assemblies 190, 290 or 390, with the shielded bearing being sold separately. Thus, a manufacturer, supplier or retailer need not produce and/or carry all three embodiments of fully assembled casters 100, 200, 300, but instead may only carry the aforementioned kits and/or individual components thereof.
[00035] Furthermore, a caster 100, 200, 300 in accordance with the present invention is amenable to repair in the event of damage to one or more of its components. For instance, if the shielded bearing 120 is worn or damaged, one may disassemble the caster mounting assembly, remove the retaining ring from the groove, replace the old shielded bearing with a new one, insert the retaining ring back into the groove, and reassemble the caster mounting assembly. Replacement of other components may also be performed, thereby obviating the need to toss out the entire caster in the event that a single component is worn or damaged.
[00036] The foregoing disclosure provides illustrative embodiments of the invention and is not intended to be limiting. It should be understood that modifications of the disclosed embodiments are possible within the spirit and scope of the invention, and the invention should be construed to encompass such modifications.
